To all whom t may concern: Be it known that I, CAL SPEISER, a citizen of the Swiss Republic, and resident of Gelterkinden, near Basel, Switzerland, haye invented [new and useful Improvementsin Looms, of which the following is a full, clear, and exact specication. l

The invention relates to a loom in `which the warp is obliquely upright and the heddles for forming the shed, instead of being suspended, arein an inclined or oblique position and have the form of rigid harness frames sliding in a guide frame, whilevthe lay is arranged below the heddles and moves in an.upwardlyinclined direction, instead of horizontally.Y In sucha loom the warp is most conveniently inspected and easily accessible, which is veryv advantageous for the weaver in respeci; both of'health and labor. Moreover, since the heddles are not suspended the numerous heddlecords, wires and the like are eliminatedY and the weight of the heddles is toa great extent without eect, so that they can be moved'more quickly than suspended heddles. Further,4 as the lay is arranged belo-w ,the heddles, the latter are easily accessible andy visible. Finally, the loom can in. many eases bev better arranged inthe'V mill than formerly and more easily superintended. Y

The new construction of loom is appropriate' for all. kinds of yarn', wool,- cotton, silk, waste silk, flax, paper or the like. It is applicable for cloth looms or for ribbon looms of any ribbon breadth, and for all' kinds of fabric, such as taffeta, figured fabric,.velvet or the like.

The accompanying drawings show, as an example of the invention, a ribbon loom having a. tappet motion for the heddles.

atil and the shed isat- 2. The hedidles, are arrangedin an inclined position one above the other and are formed by rigid harness frames 3 (Figs. 4L, 5, 6) which are'guided rectilinearly in a guide frame 5. At their forward ends the harness frames 3 are v grooved to receive heddle frames 6 which are pushed into place and are retained by spring catches 7 that can be operated by hand to permit withdrawal ofthe heddle frame. have the usual eyes through which the warp threads are threaded according to the number of ribbons and to the kind of shedding in the well-known manner so that those threads of the different ribbons vwhich are to share the same shed extend'through eyes of heddles in the same heddle frame.

The harness frames are moved for example by a tappet motion. The mechanism here shown comprises, as usual, a number of tappet levers 8 'corresponding with the number of harness frames and connected with them. respectively Vby rods 9; in Fig. -1 only the last lever at each end of the row is shown, for the sake of clearness. of the several tappet levers 8 with the corresponding lharness frames 3 is shown diagrammatically at 10, Fig. 3. The levers v8 TheV heddles in the heddle frames The connection are mounted to turn onan inclined shaft 11 suitably arranged in the lowerpart of the on itslever is suchthat the harness frame connected with each lever receives the stroke necessary for proper formation ofthe shed; that is to say, the stroke ofthe upper harness frames which are farther from the fell of the cloth is greater than that of the lower frames, lin order to form a cleanshed. The tappets 13 are fixed to a. shaft 14 (Fig. 2) which is transversely; divided; the tappets Vforming two groups on'this shaft, those `of one group, for instance those used for' grounding, being connected with one half of the shaft by means of acollar 15 fixed thereon and of coupling bolts 16 oarriedby said Collar, while those of the other group, for instance those used for border formation, are connected by means of another collar 17 and coupling bolts 18 with the other half of the shaft. The halves of the shaft 14 are each driven by a separate toothed gearing A19, 20 of variable ratio, and through two bevelVK pose of afprolonged open shed, is

rtionship in respect of their rotation for ing pulley 29 through toothed gearing 28.- e

This arrangement permits of bringingthe two groups olf tappetsinto the shedding work. Y

Y. rIhe strokes which the levers -8 -perform under action of the springs l2 is adjustable Vby lscrew stops 43.Vv

y The lay l30, instead of moving to and fro in a more or less substantially horizontal plane, moves up .and down `in an upwardly inclined direction. It -is placed below the harness frames and rocked on an aX-is 31 by a grooved eccentricl, which, for the purdriven in known manner by means of a pair ofreccentricallyr journaled ltoothed wheels The weight of the lay is for the most part borne by the corresponding springs 44 fixed to theframe of the loom. .The throw of the shuttle is notnewg. any desired kind of .mechanism maybe used and therefore none Y is shown in the drawings. Ity may, however,

be statedfthat the shuttle will be slidably connected' withv thefraceway of the lay by means of'a'known' groove and claw 'connection so as to be prevented from falling 'out'offplace The beating of the weft takes the harness frames, at 34.

place below pass around the drum The ribbons mayv '85 which ,in conjunction with the pressure y roller 36and the counter-roller 37 exertsl the a pull on the ribbons and allows themV to Yrun 1 Vof the loom,

on to a frictionv drum .88. The Ylower part however7 offers sufficient l space for a friction reel 39 on to which the ribbons can run if necessary.

Fig. 1.' shows two modes vof delivering the warp threads. ,One consists ofspools 40,7the other ofwa'rp rollers 41. From either store of warp the threads aref drawn downward,

'withfhardly any Contact or friction, over the Y Y guide rods 49.
